    You can header wrap short sections of unjacketed exhaust.

    To keep water out of the exhaust you will have to jumper the water around connections. Dump the water in the exhaust tip through the transom

    This is a jacketed 180 degree elbow with an O2 sensor bung that I made. You could make (or have made) a 90 degree elbow, which would be easier. Inner tube is a mandrel-bent 3" O.D. piece. Outer is 4" O.D. which had to be sectioned, since the bend radii were different. There is a short piece that is uncooled where the O2 bung is welded on, so you couldn't run this under a closed compartment, unless you made a water-cooled shield to clamp over the uncooled segment.

    This is what I was thinking of doing and I'll let you guys tell me if it's ridiculous or not lol. What if I had a spacer made to go between the turbo and the Banks elbow? This way I only have to have one item fabricated and can pretty much keep what I have. I know it might not look the best having one side sticking out farther than the other but at the end of the day, no one will see this engine under the cover and I'd rather have the engine tuned right than have it look pretty.

    I appreciate the feedback. Thanks guys.

    That is a good idea and it might be my best bet. I was hoping to use that FiTech EFI kit though which means I would need the o2 sensor permanently. I really wanted to go that route for piece of mind but I might just have to go with a carb.

    I have the elbows that are shown on the right in this pic. The water is introduced to the exhaust just before the hose connection as shown in the 2nd pic.

    If I can find something like the set in the middle of this pic, I wonder if that will work.. Then just use a small piece of rubber hose to connect to the exhaust tip.

    Borla or pay a visit to a good muffler shop

    Most dyno shops just run the engine and you bring your own tuner. They can't take responsibility for an engine failure

    Unfortunately that is not something I can build on my own. Are there any companies that can make custom water jacketed pipes?

    Thanks for the reply -How much pipe are we talking between the sensor and where water is introduced? It appears that the gale banks exhaust isn't going to work with an o2 sensor. I might have to scrap the turbo idea until I can figure something else out. I don't want to run boost without know my A/F ratio and I need an exhaust that will stay cool under a hatch.


    For the sake of argument -when the engine is running the exhaust is forcing the water out and when the engine stops so does the water flow. I don't see how the water will ever get back to the sensor?! Am I missing something?

    Can you do it at the inlet to the turbo? Maybe make a short spool piece to go between the turbos and the exhaust manifolds?

    I have NO turbo experience, but the AEM wide-band sensor set-up has proven to be very reliable for my N.A. junk. And it's not that expensive either.
